If you checked the thread follow-ups, you'd see that *decreasing* spins_per_delay was not beneficial. Instead, try increasing them, one step at a time: (take baseline measurement at 100) 250 500 1000 1500 2000 3000 5000 ... until you find an optimal level. Then report the results to us! -- -Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
